| 中文摘要 | the authors presented a simple colorimetric assay for the detection of toxic heavy metal lead(ii) ion(pb2+). pentapeptide, cysteine-alanine-leacine-asparagine-asparagine(calnn), functionalized gold nanoparticles(gnps) were aggregated in the presence of the divalent metal ion in solution by an ion-templated chelation process, which caused an easily measurable change in the absorption spectrum of the particles. typically, mono-dispersing gnps exhibit an absorption band at 522 nm, corresponding to a red color solution, while aggregated gnps have it at longer wavelengths, corresponding to a purple or blue color solution. the chelation/aggregation process is reversible via the addition of a strong metal ion chelator such as edta. highly selective and sensitive detection of pb2+ in aqueous solution is thus provided. a detection limit of 0.1 mu mol/l of pb2+ was demonstrated. |
